Position and presence detecting device for stacked sheet members

A position detecting device for stacked sheet members, comprising:

• a sheet stacking member for stacking thereon sheet members transported thereto;
• drive means for driving said sheet stacking member to displace the position thereof;
• sheet detecting means positioned in such a manner as to detect the passage of the sheet members thus transported and to detect the upper end of the sheet members stacked on said sheet stacking member;
• and
• identifying means adapted to displace said sheet member upon identification, by means of the output from said sheet detecting means, when the upper end of the sheet members stacked on said sheet stacking member reaches a determined position.

A position detecting device for stacked sheet members, comprising:

• transport means for transporting sheet members;
• a sheet stacking member for stacking thereon the sheet members transported by said transport means, said stacking member being rendered vertically displaceable;
• sheet detecting means for detecting the upper end position, at an end facing said transport means, of the sheet members transported by said transport means and stacked on said sheet stacking member, and also for detecting the passage of the sheet members transported by said transport means;
• and
• identifying means for lowering said sheet stacking member by a determined amount upon identification, by the output of said sheet detecting means, of the arrival of the upper end of stacked sheet members at a determined position.
